Abstract The reaction of S 4 N 4 with PdCl 2 in methanol yields among other products the dinuclear complex Pd 2 (S 3 N) 2 (S 3 N 2 ) (D): dark red needles, space group R"3̄ with a = 32.759(15), c = 6.516(4) Å and Z = 18. The structure of D was determined by an X-ray analysis. Each palladium atom is part of an almost planar PdS 3 N metallocycle. The SNSNS group acts as a bridge whereby each of its terminal S atoms is bonded to both Pd atoms. The Pd atoms possess a square planar coordination by four S atoms. The coordination planes form an angle of 114.9°. The Pd-Pd distance of 2.921(2) Å is rather short.
